Facebook
Facebookis a tool that connects people with friends and others who work, study and live around them. Millions of people use Facebook everyday to keep up with their friends, upload an unlimited number of photos, share links and videos, and learn more about the people they meet. Facebook can be kept private or can be open to many.
Why use Facebook?
Many people call Facebook their “home” on the Internet. It's a place they can go to leave you a message, browse through your photo collections, or even chat with you while you are online. It is seen as be a great way to keep in contact with friends and family, and even find long lost friends that you haven't spoken to in years.
The Facebook "wall" is where it all happens. This is where you write comments on what you are up to or share photos and articles with your friends. You'll also see what your friends and family are posting on their "wall". Anyone on your friends list can come by and write a comment on your wall. So not only is the Facebook wall a place to let everyone know you are back from vacation and post trip photos, it is also a place where conversations can be started.

Twitter
Twitter is a social networking and microblogging service that allows you answer the question,"What are you doing?"by sending short text messages 140 characters in length, called "tweets", to your friends, or "followers."
The short format of the tweet is a defining characteristic of the service, allowing informal collaboration and quick information sharing that provides relief from rising email and IM fatigue. Twittering is also a less gated method of communication: you can share information with people that you wouldn't normally exchange email or IM messages with, opening up your circle of contacts to an ever-growing community of like-minded people.

Wikispaces
Wiki's are a great way to get your voice heard on the Net. You can start a wiki about anything you want. A wiki allows you to discuss something that's important to you, while at the same time getting opinions and information from other people that visit your wiki. Wikis allow your readers to become part of your Web site by letting them add their ideas and information to the wiki too. The best part about a wiki, you don't need to learn any new software, or install anything, or upload any files to your computer. You also don't need to know HTML or any other type of programming language. You just need to type into your browser.
Just as with a webpage you can add images, audio, files and links to a wikispace, making it a very interactive site for communication.

Blogs
A blog is a personal diary or journal published on the world wide web consisting of discrete entries called "posts’. These are typically displayed in reverse chronological order so the most recent post appears first. Blogs are usually the work of a single individual, occasionally of a small group, and often are themed on a single subject. Although not a must, most good quality blogs are interactive, allowing visitors to leave comments on the blog. It is this interactivity that distinguishes them from other static websites.[In that sense, blogging can be seen as a form of social networking. Indeed, bloggers do not only produce content to post on their blogs but also build social relations with their readers and other bloggers.
